What is the advantage of using a food chain as a model to represent an ecosystem?

The advantages of using a food chain are

. Explains the natural flow of energy
. Gives info about every animal in it
. Does so in an organized and easy to understand manor
. Tells you what animals are the best predators
. Tells you which animals are herbivores, carnivores, and omnivores











How is a food chain different than a food web?
The difference between a food chain and a food web is that a food chain shows what eats what and does not have many links where as a food web shows the transference of energy between biotic and abiotic factors of the ecosystem and has many links on the chain.
Many food chains combined make up a complex food web.
